1. A method by a user equipment (UE) in a wireless communication system, the method comprising:
- receiving configuration information for configuring a power headroom report (PHR) from a base station, the configuration information indicating whether a PHR format for the UE is an extended PHR;
identifying whether the PHR format for the UE is the extended PHR based on the configuration information;
if the PHR format is the extended PHR,generating the extended PHR including a maximum transmission power generated based on a power management-maximum power reduction (P-MPR) and an indicator indicating whether the UE applies the P-MPR when determining a lower limit of the maximum transmission power, andtransmitting the extended PHR to the base station; and
if the PHR format is not the extended PHR,generating a normal PHR without the indicator, andtransmitting the normal PHR to the base station.

Abstract
A method and an apparatus for efficiently transmitting or reporting a Power Headroom Report (PHR) of a User Equipment (UE) are provided. The method of transmitting the PHR of the UE in a mobile communication system includes configuring an extended PHR including an indicator corresponding to a variation factor of a maximum transmission power of the UE, and transmitting the extended PHR from the UE to a Base Station (BS). The BS may be notified of a maximum transmission power of the UE and a variation factor corresponding to the maximum transmission power in order to enable efficient scheduling.

5. A user equipment (UE) in a wireless communication system, the UE comprising:
a controller configured to; receive configuration information for configuring a power headroom report (PHR) from a base station (BS), the configuration information indicating whether a PHR format for the UE is an extended PHR, identify whether the PHR format for the UE is the extended PHR based on the configuration information, if the PHR format is the extended PHR, generate the extended PHR including a maximum transmission power generated based on a power management-maximum power reduction (P-MPR) and an indicator indicating whether the UE applies the P-MPR when determining a lower limit of the maximum transmission power, and transmit the extended PHR to the base station, and if the PHR format is not the extended PHR, generate a normal PHR without the indicator, and transmit the normal PHR to the base station. - View Dependent Claims (6, 7, 8)

9. A base station in a wireless communication system, the base station comprising:
-
a controller configured to generate configuration information for configuring a power headroom report (PHR) to a user equipment (UE), the configuration information indicating a PHR format the UE is an extended PHR; and a transceiver configured to; transmit the configuration information to the UE, and receive the PHR corresponding to the PHR format from the UE, wherein the received PHR is the extended PHR including a maximum transmission power and an indicator indicating whether the UE applies a power management-maximum power reduction (P-MPR) when determining a lower limit of the maximum transmission power, if the PHR format for the UE is the extended PHR, wherein the received PHR is a normal PHR without the indicator if the PHR format for the UE is not the extended PHR. - View Dependent Claims (10, 11, 12)

13. A method by a base station in a wireless communication system, the method comprising:
-
generating configuration information for configuring a power headroom report (PHR) to a user equipment (UE), the configuration information indicating a PHR format for the UE is an extended PHR; transmitting the configuration information to the UE; and receiving the extended PHR from the UE; wherein the received PHR is the extended PHR including a maximum transmission power and an indicator indicating whether the UE applies a power management-maximum power reduction (P-MPR) when determining a lower limit of the maximum transmission power, if the PHR format for the UE is the extended PHR, wherein the received PHR is a normal PHR without the indicator if the PHR format for the UE is not the extended PHR. - View Dependent Claims (14, 15, 16)
